Embodiment Construction
[0022] exist figure 1 A schematic diagram of a motor vehicle cooling circuit 1 according to a preferred embodiment is shown schematically in . A hydrodynamic retarder 3 is arranged in the cooling circuit 1 , comprising a main impeller 4 and a secondary impeller 5 , which form a torus-shaped working chamber 6 . The cooling medium of the cooling circuit 1 is simultaneously the working medium of the hydrodynamic retarder 3 . In this case, the secondary impeller 5 is designed to be stationary. Alternatively, the reducer 3 may also be designed as a counter-rotating reducer. The main impeller 4 is here driven in rotation by an auxiliary drive 12 of the transmission 8 , which is drivingly connected to the drive shaft of the drive motor 2 . The retarder 3 is therefore designed as a secondary retarder and brakes the motor vehicle depending on the driving speed. Alternatively, it is of course also possible to design the gear unit as a final gear unit and brake the motor vehicle as a...
